Expressioni

Tissue specificityi

Brain (at protein level). The alpha/alpha homodimer is expressed in embryo and in most adult tissues. The alpha/beta heterodimer and the beta/beta homodimer are found in striated muscle, and the alpha/gamma heterodimer and the gamma/gamma homodimer in neurons. In striated muscle, the fiber-type order of ENO3 expression is IIB > IIX > IIA > I.2 Publications

Developmental stagei

During ontogenesis, there is a transition from the alpha/alpha homodimer to the alpha/beta heterodimer in striated muscle cells, and to the alpha/gamma heterodimer in nerve cells. In hindleg muscle, first expressed at E15 after which, levels increase sharply between E15 and E17. A steep prenatal rise in expression accompanies the formation of secondary myofibers and the development of innervation. High levels continue throughout newborn and adult stages. Beginning at postnatal day 5, a second sharp increase in expression correlates with the definitive specialization of the myofibers. Later in development, mainly expressed in fast-twitch fibers. In cardiac muscle, first expressed in the embryo in the cardiac tube.2 Publications

Inductioni

Levels decrease in degenerating myofibers, and increase with their regeneration.

Interactioni

Subunit structurei

Mammalian enolase is composed of 3 isozyme subunits, alpha, beta and gamma, which can form homodimers or heterodimers which are cell-type and development-specific. In vitro, interacts with several glycolytic enzymes including PKM, PGM, CKM and ALDO. Also binds PLG and troponin, in vitro. Interacts with PNKD (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
